Answer / rabi

Neutral- it is a point where the sum of the current meeting
at that point is zero. E.g. in three phase star connected
winding the neutral is the point where all winding is
meeting at a same point obviously at normal operating
condition.
Ground- ground and earth both are same term. it may be a
reference point for in an electrical circuit from which
other voltages are measured, or a common return path for
electric current, or a direct physical connection to the
Earth.
Earthing -it is nothing but the process of connecting all
the neutral points of the equipment and non-conductive
exposed part of the metal structure to earth.

Answer / kalidassallinterview

Earthing : To connect the machinery body to ground by a
conductor it is called earthing.

Ground : Ground is a one terminal, it having zero volts.

Neutral: The junction of 3phase. In balanced condition this
voltage is zero.

Earthing: to protect from shock we have toe earth all the equipement and ins. Include AC,socket

Ground: to protect equipement body we have to ground it..

Neutral: it is completing the ckt.

Answer / harshad pingle

Neutral= 0=In=Ir+Iy+Ib i.e summation of three currents
equals to the neutral current which is zero.

Grounding= Zero potential point. It may be the floating
neutral of star connected system.

Earthing= The system connected to earth where the system
max leakage current can flow.

Answer / sendhur

Ground and earth are one in the same, and don't normally
carry any current - they are "reference" ground.

Neutral is the grounded side of an AC outlet. It carrys
current, it is the return path for AC. Although it is
grounded at the utility pole, it should not be grounded
anywhere e

EARTHING: it is defined as connecting the metal body or non current carrying part of electrical installation to solid mass of earth

Answer / rehan khan

in Earthing system we connect the system with the earth pysically for the sake of safety . while ground is not physically connected to earth but is a reference potential point and return flow path for currrent from different parts of circuit.........

Answer / pankaj agarwal

earthing means neutral earthing. it is connecting the
current carrying points in the circuit to earth. this is
done for the purpose of operation of earth fault relays.

grounding means equipment earthing. it is connecting tha
non current carrying parts, like metallic enclosure, to the
earth. this is done for personnel safety.

neutral is a common return path in a multi phase circuit,
generally earthed to provide a reference voltage.

Answer / ihtesham

all ans is correct according to my knowledge.
neutral at zero potential point
earth at positive potential point
grounding at negative potential point

How do we measure earth fault current in Generator Transformer(20/420kv),Station Transformer(20/11 kv) and Unit Transformers(20/11kv) for our plant system, since these don't have any Neutral earth Fault relay connected to their Neutral Earth? But for Unit Service transformers(11/.433 Kv) we have an Earth Fault Relay connected to its neutral earth.Why is such so?
